I don't think solder on traces helps. That is not an issue. Issue would be mosfets ratings, their temperature when working at high current, heat dissipation. Thick traces would be overkill. Adding small fan or heatpipes would help with the heating.
@vladk38792 жыл бұрын
yeah it's more than just beefing up the lines and changing mosfets as you don't exactly know which ones are best seen a guy on reddit talk about particular mosfets he used and they didn't burn after few km)) but for my application it might not help as I'm using 48v battery....

Cool stuff really useful to get tried and tested advice on the settings. I have 3 controllers in a box somewhere, I'm gonna give this a shot see if I have the beefy traces too. My m365 is a 1s running the pro custom firmware, so I'm guessing it doesn't have the traces beefed up. There's a nice guide on scooterhacking's wiki on swapping mosfets and caps to support higher battery voltage (12s basically), might try that for next summer.

I actually got my original controller (which was the best one i recon) burned up from over-use as it broke originally. That's not just my bad, but what i ordered was lied about and i never got a new original pro2 controller. I did however charge my pro2 up to the max from nothing and went for a ride down-hill. Breaking at certain sections fryed the rails. I could then see that reinforcing it could have saved me that time. But i am afraid it wouldn't matter anyways since it can happen again if the scooter is too hot, max battery, and you break a lot down-hill right after you hit max charge. I still did repair my older controller, i got 3 but 2 works and my original is dead. If the controllers are lacking anything in my opinion, it has got to be cooling solutions with how horribly hot they tend to get randomly.

I was thinking of doing this with my Aovo 365(clone) but they encapsulated the whole board:( -You would think 0n this that they'd screw the FETs down and use a blob of Angel sh*t (heat transfer compound) on the thermal feedback at least wouldn't you? It might be worth trying, you might get a few more Amp out of it yet-just make sure you use screw insulators when screwing down the fets,TBH the heatsink looks a bit pap-I'd be tempted at something like a CPU cooler or even 3 little ones-1 for each phase, I'm going to see if I can get some Xiaomi esc's-I've got extra battery, Motor and an urge for a fast 2wd :) . All the best.

with the thermalpads remove capton tape inside controller put a long strip 0.5mm-1.0mm thermalpad instead of the captontape(make sure the fets is not in direct contact with housing cover bit extra length/with on the pad to prevent it, under controller housing dont use thermalpads they are not as effective as thermal compound.

You should get a spade or a knife tip for this sort of work that tip isn't ideal and maybe also look into upgrading those MOSFETs just make sure the controller doesn't use the MOSFET's Rds on for sensing. current.

I have an M365, and I did the same thing, not quite as thick with the solder, but I added some bus bars. Then I added another battery in parallel, and my wife scooter is the exact same thing, but no mods completely stock controller stock battery. all I did was change the firmware on the battery and put custom firmware on the controller. the same exact firmware that I'm using, and hers is faster. Lol, the only difference between the two scooters is hers has stock tires and I have 10 inch tires. It has to be the tires. I'm happy with the speed overall. I don't think there's really a need to go much faster. it'll do 29kph. But I weigh 200 lb, and I want a little more power to go uphill. I'm thinking about reinforcing my controller to go to 72v but just limiting the amperage to like 25ish amps.... according to what I've read 35 is about the Max. But even if I run 72 volt at 18 amps its still twice the wattage.

I had it on good authority that it needs reinforcing to go to 35 .. when opening my pro2 I did notice that it was already reinforced .. but there still were narrow spots on the main power traces .. so .. my advice would be to reinforce yours .. pour as much solder as you can to make sure no hot spots form you'll be riding with way more peace of my that way

Why the hell did you put Thermal pad on the back of controler. New thermal paste is the right solution like on computer CPU. You won't EVER see pads there. Youcan put 1 mm thermal tape under mosets ( but remove original yellow tape from there (it has worse thermal conductivity than thermal pad)
